132min=2h 12min
15:35 + 2h 12min=17:47
Answer:
31.5 in
Step-by-step explanation:
- Volume of a hemisphere = (2/3)
r³
(where r is the radius)
- Volume of a cylinder =
r²h
(where r is the radius and h is the height)
- radius r = (1/2) diameter
First, find the volume of the scoop using the volume of a hemisphere formula with r = 21:
Volume = (2/3)
x 21³ = 6174
in³
Now equate the found volume of the scoop to the equation of the volume of a cylinder with r = 14, and solve for h:
14²h = 6174
196
h = 6174
Divide both sides by
: 196h = 6174
Divide both sides by 196: h = 31.5
Therefore, the height of the molten steel in the storage tank is 31.5 in
C because if you plug one into the other the answer comes out as x and that is how you know it is an inverse

b. (4,1/2)
Step-by-step explanation:
Answer:
solution:
x = pounds of cashews = 20
y = pounds of peanuts = 70
Step-by-step explanation:
x = pounds of cashews
y = pounds of peanuts
---
4.75x + 2.50y = 3.00*90
x + y = 90
---
put the system of linear equations into standard form
---
4.75x + 2.50y = 270
x + y = 90
